“…In comparison to all the methods mentioned before, bioreduction is eco-friendly and easy to execute. Also, the Ag-ENPs obtained exhibit more excellent stability utilizing a green synthesis using methanol extract of Citrus limetta peel (Maboya et al, 2019 ); silver ions yield high biocompatible that can be handled in biomedical settings without significant adverse effects (Vijayakumar et al, 2020 ).…”

Graphical abstract Currently, hundreds of different nanomaterials with a broad application in products that make daily lives a little bit easier, in every aspect, are being produced on an industrial scale at thousands of tons per year. However, several scientists, researchers, politics, and ordinary citizens have stated their concern regarding the life cycle, collateral effects, and final disposal of these cutting-edge materials. This review summarizes, describes, and discusses all manuscripts published in the Journal Citation Reports during the last 10 years, which studied the toxicity or the effects of nanomaterials on human and environmental health. It was observed that 23.62% of the manuscripts analyzed found no ecological or human risks; 54.39% showed that several nanomaterials have toxicological effects on the ecosystems, human, or environmental health. In comparison, only 21.97% stated the nanomaterials had a beneficial impact on those. Although only 54.39% of the manuscripts reported unfavorable effects of nanomaterials on ecosystems, human, or environmental health, it is relevant because the potential damage is invaluable. Therefore, it is imperative to make toxicological studies of nanomaterials with holistic focus under strictly controlled real conditions before their commercialization, to deliver to the market only innocuous and environmentally friendly products.

“…ZnO spectrum exhibited a UV absorption band at 360 nm, which is a characteristic absorption peak of ZnO (Ramya et al 2018). Ag exhibited a surface plasmon resonance (SPR) peak at approximately 404 nm (Das et al 2016;Vijayakumar et al 2020). However, the Ag/ZnO (5% Ag) absorption spectrum (in Figure 4(a)) was not a simple superposition of single materials spectrum.…”

In the present work, the performance of Ag/ZnO/CoFe2O4 magnetic photocatalysts in the photocatalytic degradation of Ibuprofen (IBP) was evaluated. This study considered the use of pure Ag/ZnO (5% Ag) and also use the Ag/ZnO/CoFe2O4 magnetic catalysts containing different amounts (5, 10 and 15% wt) of cobalt ferrite (CoFe2O4). The catalysts were characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and photoacoustic Spectroscopy. To carried the photocatalytic degradation reaction, different concentrations of the ibuprofen contaminant solution (10, 20 and 30 ppm) and different concentrations of photocatalyst were tested (0.3 gL−1, 0.5 gL−1 and 1.0 gL−1). The reaction parameters studied were: IBP concentration, catalyst concentration, adsorption and photolysis, influence of the matrix, radiation source (solar and artificial) and the effect of organic additive. At the end of the photocatalytic tests, the best operation conditions were defined. Considering the obtained results of degradation efficiency and magnetic separation, the optimal parameters selected to proceed with the other tests of the study were: ibuprofen solution concentration 10 ppm, Ag/ZnO/CoFe2O4(5%) catalyst at a concentration of 0.3 g L−1 and pH 4.5 of the reaction medium. The results indicated the feasibility of magnetic separation of the synthesized catalysts. A long duration test indicated that the catalyst exhibits stability throughout the degradation reaction, as more than 80% of ibuprofen was degraded after 300 minutes. The photocatalytic activity was directly affected by the ferrite load. The higher the nominal load of ferrite, the lower the performance in ibuprofen degrading. It was also observed that the smallest amount of ferrite studied was enough for the catalyst to be recovered and reused. The adsorption and photolysis tests did not show significant results in the IBP degradation. In addition, it was possible to verify that the aqueous matrix, the use of solar radiation and the addition of additive (acid formic) interfered direct in the process. The catalyst reuse tests indicated that it can be recovered and reused at least three times without considerable catalytic activity loss.

In the present study, Tl4HgI6 nanostructures have been successfully fabricated through a simple precipitation route. The impact of TlI stoichiometric ratio to HgI2, and kind of surfactants was explored on purity, structure, and shape of samples. The as-fabricated Tl4HgI6 was characterized via XRD, EDX, FESEM, TEM, HRTEM, and Raman spectroscopy. Raman spectrometry corroborated the XRD outcomes, and revealed that the Tl4HgI6 nanoparticles were successfully fabricated. The structure, shape, and scale of the products were studied through FESEM images. It was observed that different factors have a notable aspect on the morphology and size of the products. The maximum antibacterial activity of Tl4HgI6 was perceived against S. aureus, E.coli and M. catarils. These outcomes demonstrate that Tl4HgI6 displays efficient bactericidal activity against Gram-positive and Gram-negative microorganisms. The anti-biofilm activity revealed that the best reduction of biofilm was recognized in higher Tl4HgI6 concentrations (2×MIC). Tl4HgI6 at 2×MIC concentration inhibits biofilm production by S. aureus and E. feacalis with an inhibition percentage of 95% and 90%, respectively.
